|MPRovl-:D FaUlT-DRYING OVEN.

Specification forming part of Letters Patent No. 114 324, dated September 20, 1864.

To all whom -t may concern Be it known that we, DAVID LIPPY and SAMUEL LINN, ot' Mansfield, in the county oi' Richland and State of Ohio, have invented a new and Improved Oven for Drying Fruit; avid we do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, Inaking a part of this specitication, in which- Figure l is a longitudinal vertical section ot our invention, taken in the line a' a, Fig. 2; Fig. 2, a horizontal section of the same, taken in the line jl/ y, Fig. l; Fig. 3, a transverse vertical section of the lower part of one side of the same, taken the line e z, Fig. 2.

Similar letters of reference indicate like parts.

The object of this invention is to obtain a device by which fruit may be dried with rapidity and in a thorough manner; and to this end the invention consists in providing an oven with a series of iiues and registers, and arranging the same with the re-box and a drum in such a Inanner that the fruit, which is placed in drawers or on shelves within the oven, will be exposed to the requisite degree of heat -to expel moisture from them and due provision made for the escape of the moisture.

A represents a Iirebox, of rectangular form and of any required dimensions; and B is a chamber of the same length and breadth as the tire-box, but made shallower. The chamber B is on the top of the tire-box, and has a register, a, at each side of it, and also has two registers, b l, at its top. (See Fig. l.)

O is the oven, which is placed on the top of the chamber B, and may be of any suitable dimensions. On the top of the oven there is a drum, D, with which the smoke-pipe E communicates; and F is a pipe, which communicates with the drum D and the tire-box A, as shown clearly in Fig. 1.

G represents a series of vertical dues, which are arranged in three rows, extending transversely across the ue, as shown in Fig. 2,

ber B, as shown in Fig. 1. Underneath each row of flues G there is a register, H, and there are registers I at the sides of the oven C,

and at one side of the oven C there is a door, J.

'lhe oven C may be secured on the chamber B by means ot' any suitable fastenings.

In the oven C there are placed two or more tiers ot shelves or drawers, K. These shelves or drawers are placed one over the other on cleats c, so that they may be drawn out of the oven and placed within it through the doors J with the greatest facility, and the shelves or drawers may be provided with perforated bottoms, it' desired.

From the above description it will be seen that when a re is kindled in the {ire-box A the products of combustion will pass up through the lues G and pipe F into the drum D, and thence into the pipe E, the latter being the chief passage for the smoke and other products of combustion, the heat chiefly pass ing up through the lues G. By this arrange` ment the oven is heated evenly throughout, the heat passing between-the shelves or drawers K and up through the fruit therein. The moisture expelled from the fruit is carried o" by air, which passes into the chamber B through the side registers, a, is admitted into the oven through the top registers, b, and escapes therefrom through the registers I. This current of air may be regulated as desired by the adjustment of the registers specified, and the passage of the heat through the Vtlues G may also be regulated as desired by adjusting the registers H.
